i was wanting to ask what exhaust height people like.

alll else being the same raising exhaust lets heat out for max rpm and lowers engine temperature on the positive side. on the negative side it will lower compression and worse it lets out power needed on small cylinders.

how was stock height and width working for people at max rpm??? anyone want to say something.
-also does low blowdown have consiquences besides a low powerband such as heat or something?
